Hint: Free Bridge Crossing
The guard at Cape Claw charges you a fine for crossing. Instead, drop into the water by the longneck and search for a rocket pad to access the area past the guard

Cheat List
Star Fox Adventures cheats are unlocked by purchasing tokens for 20 scarabs when you find a secret well (the first of these can be found in Thorntail Store). Once you have a token, take it to the maze that the Stone Guard (huge guy above the waterfall) lets you play in (warp to it if you're out of the area). The maze is pretty tricky, but with enough exploration you'll find another well. Use the C-stick to locate the token and drop it into the well. If you did everything right it will say "cheat activated." Unfortunately, it doesn't tell you exactly what the cheat is, so you have to surf out to the front menu and go to Options. There you will find something new opened up.
Here are the cheats and messages you can unlock:

Display End Credits -- It will roll the staff credits, but not the ending of the game.
Music Test -- Allows you to listen to music from the game.
Special Message -- About the enemy.
Set Language to Dinosaur -- Turn the language of the game to dinosaur.
Special Message -- About your future.
Sepia Mode -- Makes the game look old-timey (black and white).
Special Message -- A voice from the past.
Special Message -- Another message about the future.


Easy Win
When racing the two soldiers on Ice Mountain, try to cut in front of them before the first tunnel(this in not that hard). Once you are in the tunnel come to a complete stop. The two bad guys will not stop and run into you so many times they will explode (the tunnel is to small for them to get around you). Once they are both dead you will have unlimited time to finish

Ice Mountain: Find the cannon. Bomb the wall nearby to reveal the well inside. Pay your money to get a token.
